Hi 
 We install SOPHOS XGS 4300 device.

 Port 2 I configure Wan Port and Static is 103.20.30.41 
 Port 3 I Configure Lan Port 192.168.1.1/24 and DHCP enable. In this port if we connect laptop and checked what is my public IP its shows 103.20.30.41 
 like that Port 4 I Configure Lan Port 192.168.2.1/24 and DHCP enable. In this port if we connect laptop and checked what is my public IP its showing ip 103.20.30.41. But I need different Public IP Address that is 103.20.30.42 
 Already Added Alias IP Address in WAN Port 2.that is 103.20.30.42 to 45 
 Please tell me what is the next step to do

Hi Zabi ulla Khan : For another network 192.168.2.0/24 you may create a separate NAT rule with SNAT IP 103.20.30.42. So it will not take Interface IP 103.20.30.41 during forwarding outbound traffic over the Internet. Below Help section and RR will help on how to add the NAT rule: https://docs.sophos.com/nsg/sophos-firewall/18.5/Help/en-us/webhelp/onlinehelp/AdministratorHelp/RulesAndPolicies/NATRules/index.html How to configure firewall rule and NAT rule on Sophos Firewall v18
